PC/104 ISA insmod Unknown symbol in module

[rplankenhorn]

I am trying to install the Linux driver on Ubuntu 10.10 and kernel 2.6.35-28 and I can't get the insmod command that is in the instructions to work. When I run:

sudo insmod pcan.ko type=isa io=0x3F0 irq=10
(I changed the address to 0x3F0.)

I get back:
insmod: error inserting 'pcan.ko': -1 Unknown symbol in module

When I run dmesg, I get back this at the end:

[ 40.069116] pcan: Unknown symbol pcmcia_disable_device (err 0)
[ 40.069811] pcan: Unknown symbol i2c_bit_add_bus (err 0)
[ 40.070767] pcan: Unknown symbol pcmcia_unregister_driver (err 0)
[ 40.073165] pcan: Unknown symbol pcmcia_loop_config (err 0)
[ 40.076390] pcan: Unknown symbol pcmcia_request_io (err 0)
[ 40.076666] pcan: Unknown symbol pcmcia_request_configuration (err 0)
[ 40.079241] pcan: Unknown symbol pcmcia_register_driver (err 0)
[ 40.079884] pcan: Unknown symbol pcmcia_dev_present (err 0)


Any ideas?

Thanks,

Hi,

which peak-linix-driver version did you use? When your systen does not have a PCMCIA interface, please build the driver without PCC support:

make clean
make NET=NO PCC=NO

best regards

Thanks for your response. I am using the 7.1 driver for the PCAN PC/104.

I tried compiling without PCMCIA support and I still get the same error. Here is the output from dmesg:

So I just compiled the driver using this command because I only need ISA support:

Code: Select all

make PAR=NO_PARPORT_SUBSYSTEM USB=NO_USB_SUPPORT PCI=NO_PCI_SUPPORT PCIEC=NO_PCIEC_SUPPORT DNG=NO_DONGLE_SUPPORT PCC=NO_PCCARD_SUPPORT NET=NO_NETDEV_SUPPORT


No I get a different error when I run the insmod command:

Code: Select all

insmod: error inserting 'pcan.ko': -1 Device or resource busy

Never mind. I got it working.

Hi,

thanks for the info. I am wondering about the I/O address of your PCAN-PC104 card, 0x3F0 is not a valid I/O address for our card. Sure you are using a PCAN card?

best regards

Michael

Yeah that was the problem. I set it up for 0x300 and was using the wrong address.
